Objectives
The goal is to understand the key RF-functionalities and related performance issues when designing the analog and digital signal processing blocks for communications receivers and transmitters. The course introduces also certain DSP algorithms that are interesting when the RF functionalities are increasingly desired to be implemented with digital signal processing.
